fiPIECIFICATION forming part of Letters Patent No. 717,853, datedJanuary 6, 1903.

Application filed January 2, 1902. Serial No. 88,082. (No model.)

To all whom it may concern:

Be it known that I, ALnXIUs HoLMns, a citizen of the United States,residing at Sacramento, county of Sacramento, State of California, haveinvented an Improvement in Photographic-Printing Frames; and I herebydeclare the following to be a full, clear, and exact description of thesame.

My invention relates to improvements in IO photographic apparatus,andpertains particularly to what are known as printing-frames. Its objectis to provide a frame adapted for use especially with films asdistinguished from glass plates. The tendency of films to curl is wellknown, and the difficulty is enhanced in the case of negatives made bythe so-called panoramic cameras, due to the proportionately greaterlength of the picture taken by the latter. These pictures vary in sizefrom four by twelve to twelve by thirtysix, and it has always been amatter of considerable annoyance to hold the edges smooth and flat inthe frame While placing the sensitized paper and pressure-board inplace.

The invention consists of a rectangular frame, a ledge on the inner wallof the fram eopening, a pressure-looard adapted to rest on said. ledgeand having a panel portion projecting into the space inclosed by saidledge, grooves formed in the ledge, and a slot in one end of the framecoincident with said grooves and through which a negative may beintroduced into the frame.

It also comprises details of construction which will be more fullyexplained hereinafter.

In the accompanying drawings, Figure 1 is a sectional view taken throughthe line y y. Fig. 2 is a top View. Fig. 8 is a horizontal cross-sectionthrough the line an 00, Fig. 1.

A represents a rectangular frame, which may be of any suitable size. Aledge 2 is formed around the four sides of the central opening, uponwhich the pressure-board 3 may rest. This ledge is provided with agroove or channel at upon three of its sides, and a slot 5 is formed inthe end of the frame, which slot is continuous and in the same planewith the channels 4. In the case of film negatives being used a suitableglass 6 is introduced into the grooves 4 through the slot-opening 5. hisglass forms a flat support for the otherwise unstable film. The latteris then inserted through the slot and its edges engaged beneath theedges of the grooves, so that it presents a smooth unwrinkled surface tothe pressure-board side of the frame. The senzitized paper to which itis desired to transfer the image is then placed upon the negative andthe pressure-board set in position and locked by means of the springmembers 7 engaging the slots 8 in the opposite sides of the frame. Thepressure board 8 has a central panel portion 9 fitting the space betweenthe walls of the ledge 2, and this panel is of sufficient depth so as topress equally and firmly on all parts of the negative, so that thesensitized printing-paper may be held properlyagainst the negative. Theaccidental removal of the glass or negative through the slot 5 isprevented by means of a button 10. The holderis equally adaptable toglass-plate negatives,

in which case the glass back 6 may be dis- 7 pensed with. A frame soconstructed is of great advantage for either plates or films. In thecase of the former the danger of accidental breakage by droppingfrom theframe through carelessness or other causes may be absolutely prevented,while in the use of films there are no curled edges or corners to annoyandirritate the operator.

In the case of a great many prints being struck from the samenegativethe invention has the great advantage over frames of ordi- 8nary construction in that the paper may be inserted and removed withgreat rapidity, as the frame may be turned or held in any positionWithout any possibility of the negative falling out.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A photographic-printing frame consisting of a rectangular framehaving a channel 95 formed therein for the reception of a nega tive, apressure-board, and means for hold ing said board in place on the frame.

2. A photographic-printing frame consisting of a rectangular frame,guides in said I00 frame for the reception of a negative whereby thelatter is supported along its edges upon its upper and lower surface,and a pressu re-board fitting said frame.

3. A photographic-printing frame, consisting of a rectangular frame, aledge on the inner Wall of the opening of said frame, a pressure-boardadapted to rest on said ledge, said ledge having grooves formed in it,and means by which a negative may be inserted into said grooves.

4. In a photographic-printing frame, a rectangular frame having groovesformed in the walls of the frame-opening and a slot extending throughone side of the frame and coincident with said grooves, said slot andgrooves adapted to receive and retain a negative.

5. A photographic-printing frame, consisting of a rectangular frame, aledge extendhand.
